Broadway icon Bernadette Peters guest stars as Ivy's mother and stage legend Leigh Conroy and pushes her daughter's buttons almost from the moment she arrives to see her daughter take center stage during a pivotal workshop for the production.

Ivy, who's still dealing with side effects of the steroids she was taking for her damaged vocal chords, lashes out at her mother after she fails to offer a note of positive feedback for her performance to the musical's investors.

In a clip exclusive to The Hollywood Reporter, Ivy realizes that she and Marilyn share a sad trait. "You're my mother and you can't even say one kind word. You know who else had a mother like that? Marilyn … and look how she turned out," a tearful Ivy says.
